I'm personally more excited about this bit. Was wrong about the 7th.Hideo Kojima has also said he will make an announcement at a special 25th anniversary event, to be held in Tokyo on August 30th. What that 'announcement' might be remains unclear, but it's said to be related to the 'vision' he has previously shared about a game that connects people.
It's so obvious there's a new Metal Gear being made, Kojima needs to stop being a troll and formally announce it!
